@LETTING MAC l=1 I To all 'whom t may concern.

Be it knownthat JAMES A. CON, a citizen of the United States, and aresident of New York city, in the borough of Brooklvn, count, of Kings,and State of New ork, and anni' MCC. donns'ronn, a citizen of the UnitedlStates, and a resident of Roselle Park, in the county of Union andState of New Jersey, have invented'certain new and useful Improvementsin Slitting Machines, of which the following is a speciication. y

This invention relates generally to slitting machines for exiblematerials and has for its main object and feature the provision ci meanswhereby' two groups ot' slitting elements may be employed in connectionwith complementary slitting' means together wlth devices whereby onegroup or' slitting elements may be adjusted to produce a diHerent widthof section while the other group 1s cooperating with the complementaryslitting` means to the end that the slitting operation may be changedfrom one width to another without breaking the 'flowing web and without. stoppingA its iiow. 'lhe broad features or" the invention hereindisclosed are claimed in application Ser. No. 678,332 liled December 53,1923. The slittino; means emplpyed may of course vary widely and may beelther ot the score-Cut or 'the shear-cut type, and, il ot the sheancuttype, the arrangement may be as disclosed in application Ser. No. 678,-334: tiled llecember 3, 1923, and some ci the claims herein are intendedto cover the disclosure of said application Ser. No. 678,334 tiledDecember 3, 1923, and also to cover some ot the features disclosed inapplication Ser. No. 678,332 led TDecember 3, i923.

ln the accompani/inf.;r drawings the inven` tion is disclosed in aconcrete and preferred term in which l is end elevation of a machineembodying the invention.

lfig. Ll is a longitudinal vertical sectional view on the plane ot lineof Fig. l..

Fig. is a diagrammatic view of a slitting operated in unison by reasonet two machine associated with a board or paper making machine and asheeter. v

The slitting devices include two sets, one

consisting here of slitting means 1 which isk `devices consists ofmember l and the group' of score-cutters 3. 'lihe two or more groups 'ofscore-cutters 2 and 3 are mounted on the carrying member l which latteris mounted to turn in a suitable support that will hereafter be moreparticularly described, and are spaced apart circumferentially on thecarrying member, beine; mounted on faces 5 and '6 of the carryingmember. llt will be understood that, it one group ot score-cutters is.in engagement or proper position with reference to member l, the othergroup may be adjusted by slidingi them along; the face of the carryingmember after which they may be secured in position by means ot screws 7,lf it is now ydesired to vary the width of the slitting sections, thecarrying member is turned in its bearings to bring said other ,sgroup olcutters into properl position with respect to member l and this can bedone without breaking; web 8 or interruptinnr its How. lin addition tothe adjustments described, it is preferred to mount the carrying memberin a snpportthat can be moved toward and away from member l; and it isalso preferred to have means to slide the carrying member longitudinallyof its anis.

As here disclosed these parte taire the fol?.

lowing forni z 9 indicates a framework in which is mounted a supporthere consisting1 ot'two' arms l() and ll. These arme are pivotallysupported on center l2. rlhe free ends ottV the arms are provided withbearings l and il and in these bearings the carrynng member l ismounted., Any suitable means may be provided to roch the but, prefereably, each arm carries a sector or io with which engage screws ll' andlp'. that can be i pairs oit bevel gears lo und handle 2U., (Jarry/ingmember l is provided with a sleeve 2i that carries e gear 22'and withthis geen meshes pinion 23, the center of which is at 12. Handwheel/,2iis connected to pinion 23 so that by turning said handwheel, thecarrying member may be turned in the bearings of the armste bring eithergroup of cutters into engagement with member 1. Mounted on one of thearms is a latch 25 that consists of a bolt 25a 'spring pressed into oneof a number of apertures 26 of the carrying member or extension thereofso that, when the carrying member has been turned toa proper position,it becomes latched in position. To withdrawthebolt, handle 27 is .turnedandn cam face 28 moves bolt upwardl and out of aperture 26'. At times,it is diasirable to be. able to move the carrying member lengthwise tocompensate for an uneven feedof material from the board mill or papermaking machine. c In order to be able to do this, extension or sleeve 21is 1n slidable engagemet with the carrying member by means of key 29 andcarries a threaded stem 30 that engages corresponding threads in thecarrying member. By turning handle 31, :tast to stem 30, the carryingmember is moved lengthwise of'its own axis in the bearings of thel arms.

In operation the preferred practice is to lower the arms away :trommember 1 and then to turn the carrying member in its bearings.4 l

In Fig. 5, the slitting machine, designated generally by 32 is shownbetween board mill or paper making machine 33 and sheeter 34. The web isled from the paper making machine over guide roll 35 and through theslitters and thence'to rollers 36 ofthe sheeter which latter rollers actto pull the web through the slitting machine.

The broad idea, disclosed herein, of score cut slitting means to severaweb into inde4 pendent longitudinal sections without distorting thesections out of parallelism together with a feeding device to exert anVequal pull on all the sections to thereby advance them in arallelism andsevering devices lto cut t e sections substantially-at right angles totheir longitudinal advance is not claimed in the present application butforms the subject matter of another appli-4 cation filed Nov. 21, 1924,Ser.- No. 751,410.
